To display the function's increment size, select the active function's key, then
I INCR SET

Example
Set a 10 MHz increment set value for RF frequency. Then decrement the 100 MHz
RF frequency by 30 MHz.

The increment value is displayed as it is entered. After the increment set value is
entered, the display returns to show the current instrument state. Note the change in
frequency value as the step key is pressed. (The digit the cursor is pointing to does not
change its value as the Step key is selected.
Refer to Knob, page 3-141, for
information about other ways to change values using the cursor positioning keys.)

Considerations When Using Increment Set with Amplitude Settings
If amplitude is displayed in dBm, and increment size is in volts, the amplitude setting
will change by the dB equivalent of the voltage increment. Similarly, if amplitude is
displayed in volts and the increment setting is in dB, the amplitude setting will change
by the voltage-equivalent of the dB increment.
0.001 uV to 2.24V (0.002 EMF uV to 4.49 EMF V) increments can be selected.
However, the Signal Generator's setting resolution is limited to the voltage equivalent
of 0.1 dB at every output level (except during Linear Amplitude Sweep, Special
Function 121)
